iziCast

iziCast is a versatile audio and video broadcaster for Chrome. It streams from internal microphone, external audio devices, audio files, and Audiobus-compatible apps to Icecast, Shoutcast, and RTMP servers. Live video from your camera can be sent to RTMP services such as YouTube, Twitch, Facebook, Telegram, and you can mix audio with video. You can also use a still image or album art to optimize bandwidth.

Features include a 16–pad soundboard, wide format support (MP3, AAC, AAC+, OGG, FLAC), level monitoring, automatic reconnect, push-to-talk, and in-app audio processing (EQ, Delay, Reverb, Limiter) as paid upgrades. It lists compatible external devices and supports multi-source mixes with per-source volumes and text overlays during streams.
